Windows 10 Anniversary may impact Microsoft .NET 3.5 preventing access to Sage 50 Accounts


Following Microsoft’s recent Windows 10 Anniversary update, some Sage customers have reported that they are unable to log in to Sage 50 Accounts after installing the update.

This may cause one of the following errors or issues:

  • The message 'You have entered an invalid password' appears

Queue.dta is in use

Please wait until this file is avaiable.
